TOPIC – SOLAR POND ABSTRACT

Energy is backbone of any countries economy as all the activities depend on various sources of energy such as coal, nuclear, wind, and hydropower. While all the sectors of energy are being developed the focus has primarily been on natural energy resources. With the current emphasis on marketisation in renewable energy utilization, development of indigenous technologies at the local and regional levels is being neglected. The increase in population and limitations on most of energy (fuel) resources has given birth to the new trends in non-conventional energy resources. Salinity gradient solar pond is one such recent technology, which seems to be both relevant and promising for world. Salinity-gradient solar technologies is a generic name given to the application of a salinity gradient in a body of water for the purpose of collecting and storing solar energy. One type of salinitygradient technology is called the salinity-gradient solar pond. Solar ponds generally utilize a one- to two meter salinity gradient and operate at moderately high temperatures. Salinity-gradient solar applications were not invented; they were discovered. The phenomenon was first observed in Transylvania in the early 1900s.Naturally occurring salinity-gradient solar lakes are found in many places on the earth. Natural salinity-gradient lakes form when fresh water flows onto salt brine and mixes to create a salinity gradient.
